I recently had a fairly invasive surgery - sufficiently so that they made me stay overnight to make sure I could walk afterwards.

During my recovery I was in a semi private room. The other occupant was named Bruce. I saw him walk to the bathroom once, but didn't see any more of him than his butt (because of hospital gowns) until we both left.

We talked a lot, though. He was almost exactly twice my age, so our views didn't perfectly align, but otherwise he was very nice.

edit: I couldn't say for certain what he was doing on the other side of the curtain but I never witnessed him eating berries or occupying a dome.
